Trifid Nebula (by Jacob Gunnarson)
The Trifid Nebula is so-called because of the dark dust lanes that divide its main section into three. The red
portion is an active star-forming region, glowing crimson due to the presence of ionized hydrogen. In the
upper left, tiny dust grains reflect the light of nearby stars. The same basic scattering mechanism that
creates earth’s blue skies give such reflection nebulae their characteristic blue color. (Taken with Small
Hall’s observatory)

The Butte-y of Physics (by Danya
AbdelHameid)
The image above is of a butte
(pronounced byoot) in Golden,
Colorado seen from the Colorado
School of Mines campus. A butte is a
tall, flat topped, steep sided tower of
rock that forms as a result of
differences in the cohesive forces of
varying rock types. The top layer or
surface layer of a butte or the caprock,
is generally composed of a very hard
rock material that is capable of
resisting erosion, as the cohesive
forces of the caprock exceed the
aerodynamic or fluid forces imposed by
water or wind driven erosion. As result,
the caprock functions as a shield for
the softer rock material beneath it and
as water and wind forces begin to
erode away the softer, less cohesive
rock material, the portion of material
shielded by the caprock remains,
producing the characteristic butte
landform.

A Night at the Movies (by Joseph Payson)Movie projectors use converging lenses to display images. The film has to be put in upside
down in order to create the correct image. The light rays are refracted by the lens, and then converge creating a real image. Light shines through the filmstrip to project each individual
frame of film onto the screen. As a person whose life revolves around film, the process is truly fascinating.

Beautiful gravity (by Irina Novikova)
The fountains of Peterhof new St. Petersburg, Russia, amazed and inspire people for almost 300 years.
It makes it all more awe-inspiring when one realizes that none of the fountains uses any pump, but just
the natural change in elevation and manipulation with the pipe sizes.

Chasing Light (by Deepak Krishnankutty)
Finally, defeated light in a race to the depths of Antelope Canyon. Light couldn't make it.

Lunar Mosaic (by Jacob
Gunnarson )
The near side of the moon is
dominated by dark plains of
basalt, which formed after the
heavy bombardment of
asteroids that pockmarked the
older highlands. This photo
was by combining three
separate photos, each made by
combining hundreds of video
frames into a single image. This
minimizes the effect of
atmospheric turbulence which
can significantly distort
images. (Taken with Small
Hall’s observatory).

Arizona from the Air (by Stephanie Wang)
This is an aerial view of Lake Mead, the largest reservoir in the US. At first, it may seem unnatural for such a large body
of water to be found in the middle of what seems like a desert. Lake Mead is a result of the Hoover Dam, which was built
to regulate the Colorado River. The Hoover Dam also provides power to over a million people. When the Colorado River
flows into a dam, the water backs up. At the bottom, it flows through a relatively small hole and water turbines generate
electric power from the water kinetic energy. Dams are just one example of how energy can change forms.

Three Spooky Spirits Come Out at Midnight (by Joseph Payson)This photo is a long exposure shot (lasting ten seconds) using a limited light source being addedand taken away by turning it on and off. In addition to this, high winds and slight movements ofthe subject create a ghostly and blurry effect despite the camera being completely focused and
still. This creates the illusion of the subject being in three places at once.

Maverick (by Katie Horn)
This photo was taken at Langley AirShow. Shown in the photo is an F-16Fighting Falcon, aka Thunderbird. Thejet is increasing in altitude, at a highangle of attack. One of the many physicsprinciples at work here is BernoulliPrinciple. The Bernoulli Principleindicates that pressurebelow the wing is higher than the airpressure above the wing. Due to thisdifference in pressure, lift is created.This lift pushes the wings upward. Otherprinciples involved are Newton’s Laws;an object at rest will stay at rest, forcetimes mass equals acceleration, and forevery action there is an equal andopposite reaction.

The Dumbbell Nebula (by Jacob Gunnarson)This nebula is the corpse of a dead star much like our sun. At the end of its life, it released its gaseous outer
layers into space. These layers now glow by the light of the remaining core of the star, the bright bluish point at the center of the nebula. Red light signifies hydrogen, while blue indicates oxygen. The shape of
the nebula is similar to that of a football, but appears as a dumbbell or apple core because we are viewing it perpendicular to its long axis. (Taken with Small Hall’s observatory).

Olympus (by Katie Horn)
This photo was taken from a home video of a storm. Lighting happens when there is a buildup of
electrostatic charge in clouds. When positive and negative charges collect and clash. Negative charges
build at the bottom of a positively charged cloud, and are then forced down to the ground making the
ground positive. This causes more negative charges to be attracted to the ground, and the constant flow
of electrons emits light, thus creating lighting. One bolt of lightning can produce around15 million volts
of electricity, and heat the surrounding air to over 60,000 degrees.

Rain or Shine (by Stephanie Wang)Typically, clouds appear as white. In this image, the clouds are an ominous grey color. This is
because it has grown thick and dense, which is the result of accumulating more water droplets and ice crystals. These thick clouds scatter more light, and less light is able to penetrate through them.
This results in the grey clouds we see.

Harp Upon the Gale (by Liz Weech)
The sound a harp makes comes from the
standing waves generated by the
plucking of its strings. In turn, these
vibrating strings cause the air within the
sound box - the harp's hollow base - to
vibrate, amplifying the sound further.

Dancing aurora in a starry sky (by Mi Zhang)Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories
of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere , where their energy is lost. The resulting ionization and
excitation of atmospheric constituents emits light of varying color and complexity.Above is copied from Wikipedia. All I know is this is a stunning, breath-taking, beautiful phenomenon.

Interference (by Irina Novikova)
Volga river (in Russia) is often wide enough so that the waves made by different vessels can
run unobstructed and interfere.

Three Suns (by James Card)
Internal reflection of light within the water molecules of the clouds creates the illusion of the sun's
rays being seen in three different locations in the sky.

Schrӧdinger’s Cat Prior to
Observation (by Stephanie Wang)
The cat “particle”, like any other
quantum mechanical system,
appears as a probability
distribution prior to
observation. Upon observation,
the wave function will collapse
into a single physical cat.

Namco Presents (by Joseph Payson)This photo was a long exposure shot involving light painted with flashlights to create an image of the classic video game character, Pac-Man, being chased by enemy ghosts. The glowing effect of the light is similar to that of a vintage arcade cabinet’s screen. For this shot, the camera recorded the mirror image of what was “drawn.” Long exposure shots work by keeping the shutter of the camera open for about 5-10 seconds, allowing for the image to be “drawn” using flashlights and the camera absorbing the light’s movement.
